Wireless connections for metropolitan networks
Svoboda, Jan ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
This Master’s thesis analizes technologies suitable for metropolitan area networks. In this thesis there are mentioned technologies used for wireless transfer with speeds above 1 Gbps. There are described basic features and parameters of microwave radio relay links in 70/80GHz range and free space optic links. These technologies are compared with classic optical networks. Practical part of thesis was focused on development of application which calculates signal attenuation caused by the passage of the atmosphere for both technologies. Results gained from this application are mentioned in this Master’s thesis.

The DPDK DNS Probe Application Extension
Doležal, Pavel ; Kučera, Jan (referee) ; Vrána, Roman (advisor)
This master's thesis is focused on extension of the DPDK DNS Probe application that monitors DNS traffic in high speed networks. It presents framework DPDK, which can be used for fast packet processing. General architecture of the DNS system is described as well as details of its components. Basic principles of transport protocol TCP are described. It introduces an effective design and implementation of DNS packet parsing to optimize DPDK DNS Probe's performance. It also introduces a design and implementation of processing DNS messages sent over TCP for export of traffic statistics. The application's performance was tested using a high speed traffic generator Spirent.

Traffic Shaping in High Speed Networks in DPDK
Doležal, Pavel ; Fukač, Tomáš (referee) ; Vrána, Roman (advisor)
This bachelor thesis is focused on traffic shaping in high speed networks. It presents framework DPDK, which can be used for fast packet processing. General traffic shaping mechanisms are described as well as traffic shaping in Linux using program tc. It also introduces a design and implementation of traffic shaper using DPDK framework for networks with 10 Gbps bandwidth. The traffic shaper uses a complex mechanism of hierarchical token bucket. The system was tested using high speed traffic generator Spirent.
